Ingsens IGS4000 series is computer-controlled, fully automatic and general purpose electrochemical measurements. The system contains an advanced MCU for digital function generator with a high speed data acquisition circuit. IGS4010 works as a potentiostat and a galvanostat while IGS4020 and 4030 have AC impedance. The potential control range is ±10 V and the current range is ±250 mA. The instrument is capable of measuring current down to picoamperes and current from microelectrode with diameter of 10 um can be measured directly without any current booster.
